I will smash the established team battle categories! The headquarters of the Interstellar Administration is located on the planet Mokai. There, as a new experiment, real-life combat games are being held between 20-meter-tall humanoid robots called Mechanical Arms. As part of the development of Mechanical Arms to advance the foundations of technology, machines from all kinds of fields compete fiercely in this professional sport. The game includes a betting element in which players predict the winner, and is called Crossfight. This new kind of sport, with its fierce battles as its selling point, is on the rise. A boy named Miuser Bugenberg enters Crossfight as an individual competitor. He aims for the top by fighting in the obstacle-ridden style of no-rules combat, called stragle. Standing in his way is Greonus Erv, a wolf-type beastman of the Assernan, who carries the bloodline of the Zazaro wolves. The boy, bearing his father's image, steps into the Crossfight arena as a swordsman. Then the two of them take on up to five regular teams. What kind of storm will the battles of Miwu and Gray, the duo known as the Twin Destroyers, stir up in Mekashin?
